Mourinho’s woes were increased after 22 minutes when the Scot spearheaded an Everton counter-attack - slamming home into the bottom corner with his left foot from 20 yards.

But the Blues were granted an unexpected lift when holding midfielder Nemanja Matic launched a thunderbolt beyond Tim Howard from 35 yards to reduce the deficit nine minutes before half-time.

And although Chelsea had a stronger grasp of the match after the break, they failed to create a clear chance before Naismith wrapped up his third of the game with eight minutes remaining to leave the Blues lingering in 16th.
